We downed this boss in 100 pulls. What an extraordinary boss this was. It was a real test of team work and coordination. In a less organized guild I can see how this boss would be an absolute nightmare. However for us it was pretty damn enjoyable. It's unfortunate Blizzard nerfed it mid-prog, which led to some re-work (and time waste) in our strategy, but overall it was very fun and rewarding to finally kill, and with a great pull count. Awesome mid-tier boss and we hope to see more like it in the future!
